O5 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE YAW RATE (YAW_RATE) PID (PARAMETER IDENTIFICATION)
NOTE: The vehicle must be on level ground and at a complete standstill. Any vehicle movement results in false values for this test.
Using a diagnostic scan tool, monitor the YAW_RATE PID
Is the YAW_RATE PID value between -0.05 and 0.05?
Yes | GO to O6 |
|---|---|
No | GO to O9 |
O6 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE LATERAL ACCELEROMETER (LAT_ACCL) PID (PARAMETER IDENTIFICATION)
NOTE: The vehicle must be on level ground and at a complete standstill. Any vehicle movement results in false values for this test.
Monitor the LAT_ACCL PID
Is the LAT_ACCL PID value between -0.4 and 0.4?
Yes | GO to O7 |
|---|---|
No | GO to O9 |
O7 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE LONGITUDINAL ACCELEROMETER SENSOR INPUT (LONG_ACCL) PID (PARAMETER IDENTIFICATION)
Monitor the LONG_ACCL PID
Is the LONG_ACCL PID value between -0.4 and 0.4?
Yes | GO to O8 |
|---|---|
No | GO to O9 |
O8 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE STEERING WHEEL ANGLE SENSOR (STEER_ANGL) PID (PARAMETER IDENTIFICATION)
Monitor the STEER_ANGL PID while slowing rotating the steering wheel one complete revolution to the left and then one complete revolution to the right.
Does the PID change in intervals of 4.5 degrees and show a 360-degree increase for each complete revolution of the steering wheel?
Yes | GO to O9 |
|---|---|
No | GO to Pinpoint Test J |
O9 CHECK THE RCM (RESTRAINTS CONTROL MODULE) INSTALLATION AND MOUNTING SURFACE
WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
